EDWARD WILLIAMS, J11, 0F 'VIREXHAM, WALES.

MEANS FOR CONTRGLLING THE OPENING OF RAILWAY-CARRIAGE DOORS.

Application filed June 7, 1916.

To all whom it may concern.-

Be it known that I, EDWARD WILLIAMS, J12, a subject of the King of England, residing at VVrexham, in the county of Denbighshire, North \Vales, United'Kingdom of Great Britain, have invented new and useful Improved Means for Controlling the Opening of Railway-Carriage Doors, of which the following is a specification.

This invention has reference to means for controlling the opening of railway carriage doors, in which there is used in connection with each carriage or coach, anactuating means adapted to be actuated by steam (or other fluid pressure) supplied from the engine, the opening of the doors being therefor controlled from the engine, or the guard or conductor of the train, or other person in authority; so that between the stations, the doors on each side of the train may be locked by this mechanism, and cannot be opened by the passengers, but when the train gets to a station all the doors can be simultaneously unlocked and freed.

The invention is illustrated in the annexed drawings in which- Figure 1 is a side elevation of a railway carriage showing the mechanism applied; Fig. 2 is a side elevation showing a fluid pressure actuator; Fig. 3 is an end View of same; and Figs. 1 and 5 show respectively right and left hand levers connected with the gear. Fig. 6 is a side elevation of the actuator showing the internal parts in dotted lines; and Figs. 7 and 8 side elevation and end view of the internal part or piston.

Referring now to the drawings, 1 represents the steam or other fluid pressure pipe, which each coach is fitted with; 2 generally designates the actuating device; 3 are the connecting rods leading from the actuator to the various locks of the carriage; 4: represents the spindles of these locks, which in themselves may be of any known suitable kind; and 5 are pivoted bell crank levers by which motion of the rods 3 is conveyed to the chains 6, connecting the levers 5 with the locks 1.

The pipe 1 is provided at each end with any suitable form of coupling, for connecting it up with the adjacent carriages in the known way.

The actuators 2 consist of a cylinder 8, within which is a piston 9, fixed on a shaft Specification of Letters Patent.

10, extending through the cylinder covers 8, and supported by hearings in them. The piston 9 consists of two disks, one at each side, with a plate 12 between them at the lower part, and a segmental shaped plate 13 extending from the plate 12 upward in each direction to the edge of the piston, so that between the plate 12, and the plates 13 on each side of it, there is formed two chambers in the lower part of the piston; and these chambers lie in the lower part of the cylinder, to which lower part steam or fluid pressure is conducted by the pipe3, through the branches 14, so that it can enter the chambers of the piston referred to, and act on the plate 12. The plate 12 also extends up from the plate 13 to the upper part of the piston, as shown in Figs. 6, 7 and 8.

The steam operates upon thepiston plate or blade 12 by impact; and the apparatus will be so arranged that the steamis only required to unlock the door by the locks 4: when the train has come to a stand-still at a station; the locks being of any knownself-locking type, which will allow the doors being closed when pressed in and locked; but only prevented from being opened.

The motor or actuator cylinder 8 is in two halves connected together by a flange 15; and the cylinder is carried from the bottom of the carriage or vehicle by a bracket 16. The shaft 10 is connected with the connecting rods 3, on each side of the actuator 2, by means of a double arm lever 18 on the shaft, and connecting chains 19; and one of the locks 4 is directly worked from the shaft 1.0 by a double arm lever 20, also on the shaft 10, and chains 21, which at their ends are joined up with the lock actuating chain 6. By this actuator, and the various rods, levers, chains, the locks of a carriage or coach can be worked from the one actuator.

The chains 6 may pass up to the locks 4 through a hole in the bottom of the carriage; and these locks may consist of a short arm or tongue fixed on a lock spindle, on which also an arm or lever is fixed, and to the end of which the chain 6 will be attached. When the said lever is pulled down by the chain, the locking tongue, which normally would engage the door at any suitable point, and in any lmown way, would be withdrawn, and so the doors will be unlocked. The lock steam or fluid pressure, comprising'a cylinspindle may pass through the frame of the der and vibratory piston or fan device therein,,operated by impact of the steam supplied to the cylinder; and connecting means between said fan or piston and locks 'on the carriage for controlling the opening of the doors; substantially'as setforth.

2. In means for controlhng the opening of railway carriage doors the COIHblIlZttlOIl of 'a motoror actuator adapted to be operated bysteam or fluid pressure COHIPIISlIlg a cylinderand vibratory piston or fan de:

vice therein operated by impact of the steam supplied to the cylinder and connecting means between said fan or piston and locks on the carriage for controlling the opening of the doors, aindconnecting rods" and levers between said actuator or niotor and various locks controlled thereby on the carriage.

I V .3. In means for controlling the opening ofrailway carriage doors the combination Copies ofthis patent may be obtained for of a motoror actuator adapted'to be operated by steam or fluidpressure comprising a cylinder and vibratory piston or fan device therein operated by impact of the steam supplied to the cylinder and connecting means between said fan or piston and locks on the carriage for controlling the opening ator or motor and the locks is efiected by double lever chains on each side of said shaft, one end of the chains being con nected to each arm.

4:. In combination, a railway car having a plurality ofdoors, a lock for each door, an actuator including a casing inclosing a vibratory element operated by fluid pressure, pipes communicating with the casing to supply fluid pressure thereto to operate the vibratory element, and connecting means between the vibratory element and the locks for controlling the opening of the doors.

5. In combination, a railway car having a plurality of doors, each door having a lock, an actuator including a vibratory element and shafttherefor, pipes'for supplying fluid pressure to V the actuator, arms extending from the shaft, and connections between the arms and the locks, whereby when fluid pressure acts on either side of the vibratory element all the locks will be released.

In testimony whereof I have signed my five cents each, by addressing the Commissioner of Patents Washington, D. G.
